There is a workaround that will allow setting custom ordering of filter items in the filter with the source Taxonomies.
With the help of this plugin you may change the order of the filter items, as our filter takes the list of category items in the same order as they are located in the category list. For example, we've changed the order of Product category items in the Custom Taxonomy Order:
Now we see the changes on the Product Category page:
Items' ordering in the filter by taxonomy was also changed:
Another workaround uses JetEngine Query Builder:
Create a Terms Query in JetEngine > Query Builder > Terms query where you can use different order options, for example:
Then you can use this query in your filter
In query variable select your taxonomy
